Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.

Claim 1

Original Legal Text

1. A method for wireless communications, comprising: indicating discontinuous reception (DRX) operation of a user equipment (UE) to allow for time-division multiplexed (TDM) operation between a first radio access technology (RAT) and a second RAT; setting a hybrid automatic repeat request (HARQ) configuration to allow for a HARQ retransmission of a packet of the first RAT, originally received in a first DRX cycle, during a second DRX cycle; and enabling the UE to enter an inactive period with respect to the first RAT to allow the second RAT to communicate during the inactive period when pending uplink HARQ retransmissions are expected during the first DRX cycle.

Plain English Translation

A method for managing multiple wireless communication technologies (RATs) in a user device (UE). The UE signals that it will use discontinuous reception (DRX), allowing time-division multiplexing (TDM) between the first RAT and a second RAT. A hybrid automatic repeat request (HARQ) configuration is set up so that a HARQ retransmission for a packet from the first RAT, initially received during a first DRX cycle, can occur during a subsequent DRX cycle. The UE can enter an inactive period for the first RAT, enabling the second RAT to communicate, even when uplink HARQ retransmissions are expected during the first DRX cycle. This optimizes coexistence of different radio technologies by scheduling their operations in time.

Claim 2

Original Legal Text

2. The method of claim 1 in which the HARQ retransmission is sent during an on duration of the second DRX cycle.

Plain English Translation

The method for managing multiple wireless communication technologies (RATs) in a user device (UE) includes signaling discontinuous reception (DRX) operation to allow time-division multiplexed (TDM) operation between a first RAT and a second RAT. A hybrid automatic repeat request (HARQ) configuration is set to allow a HARQ retransmission of a packet of the first RAT, originally received in a first DRX cycle, during a second DRX cycle. The UE is enabled to enter an inactive period with respect to the first RAT to allow the second RAT to communicate during the inactive period when pending uplink HARQ retransmissions are expected during the first DRX cycle. The HARQ retransmission described above is sent during an "on duration" of the second DRX cycle.
